Nice!
How much do you think is it worth?
Also, can I ask you something off-topic? I watched a video of yours where you compare the drops of different feather farm methods and come to the conclusion that north kryta HM is the best method overall. You only show the farm itself very briefly and the other video about the farm location you have on your channel is for NM only.
I've been trying to do it in HM using the builds from the videos description but kinda struggling with it. Wasn't sure which of the builds is the fastest and especially the fire imps at the start give me trouble in HM?
Maybe you could even make a video about it?
